Don't know if it's just me or the way MMA is going but I'm not as excited by the fights any more. In any event there is usually only 1 or 2 fights I really enjoy, it's rare to get people really going for it as if not losing is the primary concern with the fighters. It's even worse in the women's fights although that may just be due to a lack of knockout power. So many fights going the distance these days (seems like more than used to).
It's not just you, I started watching back in 2006 and i've never felt so uninterested by it. I still watch the events but find myself fast forwarding all the build up, walk ins etc. I even fast forward some fights if they're lay and prey which I would've never done before.
I think one of the main problems is the frequency of events. Back in the day it was one a month so you really got excited for it, now there's virtually an event every week. Another problem is the ground aspect isn't anywhere near as interesting now most fighters ground skills are up to speed. You don't tend to see many interesting submissions, it's either a rear naked choke or the odd arm bar here and there, if at all. When was the last time someone got an Omoplata, or a Triangle?
I have found myself fast forwarding any Womens fight that isn't one of the top fighters. The standard is so far below the men it's not even funny, ultimately it isn't enjoyable to watch.
